Osasuna are reportedly considering filing a complaint to the RFEF after seeing Inigo Martinez play 90 minutes for Barcelona in Thursday’s 3-0 win for Hansi Flick’s side.
Martinez featured after being passed fit ahead of the game following a knee injury. The issue had caused him to withdraw from Spain duty which did bring some criticism.
The situation also does not appear to have gone down well with Osasuna, according to both Mundo Deportivo and COPE.
The reports state Osasuna are considering a challenge as they think Martinez violated a rule on the period of time that must pass after an injury absence from the national team.
